Fat Asian Guy - F.A.G. - Also known as FAD (F.A.D. - Fat Asian Dude), used frequently in asian music videos, depicting a man in his early 20's leading a useless life, becoming a burden to people, or getting dumped.
The expression can be used to describe such people, even if said people is not of Asian birth!

*Discriminatory not intended*

Sometimes I could use a Fat Asian Guy, like when you have to get away from somewhere you can block the way with them! At least that way they could be useful for once!
